Solution
The alarm may be triggered by causes external to the
inverter:
- An excessive input voltage can be recorded as a condition
for bulk over voltage. In this case it is advisable to check
the inverter's input voltage and should this value be close
photovoltaic generator.
- Excessive grid voltage could cause the bulk voltage to rise in
uncontrolled fashion with a consequent protection intervention
and hence generation of the alarm. In these cases the alarm is
transitory and the inverter automatically restarts
- The alarm may be triggered by causes inside the inverter
and in this case it is necessary to contact customer
assistance.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
Once the error appears, the inverter attempts to resume
normal operation.
- Should the error occur sporadically, it may be caused by a
brusque transition of the grid voltage or of the input voltage,
but is not due to a malfunction by the inverter.
- If the error is connected to an internal fault, it will continue to
appear and so it is necessary to contact customer assistance.
- If the error signal occurs sporadically, it may be due to
causes external to the inverter (limited irradiation and so
limited power availability from the PV generator).
- If the problem occurs systematically even in conditions of
high irradiation and with
higher than the activation voltage, contact customer
assistance.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.

for the temperatures to which the inverter is exposed to return
to the operating range and for the inverter to cool down.
- If the problem persists (once the ambient temperature has
returned to within the range), contact customer assistance.
You must remember to wait for the time necessary to allow the
inverter to cool down.
- If the problem persists (once the inverter has been switched
off and back on again), contact customer assistance.

off and back on again), contact customer assistance.
